Anyone using SB Lunati cam ending in 703 Part number?

JKrebs said

If so I have a valve timing question. When adjusting the valves (first time fire up) and I'm at TDC the #2 intake is not on the bottom of the lobe. Either is the #8 exhaust. They both are close but not quite there. I don't know if the Lunati grind is a bit different. The Lunati literature calls for the intake to be adjusted when the exhaust starts to open and the Exhaust to be adjusted when to intake is fully opened. I usually use to TDC the turn 90 method but i'm concerned the a may have the cam a tooth off though i checked that more than once. I can call Lunati but i will need to wait until Monday and this will bother me. Thanks

You are on split overlap, go around, 360 crank-degrees. Split overlap usually occurs within 2 to 10 degrees or so of TDC..The 703 IIRC is a 268/276/110 fast-rate of lift cam. You probably installed it around 106, which would be 4 degrees advanced. You can verify your install by finding exact split overlap and reading your balancer, but the intake has to be off, so you can lay a straightedge across the two lifters and making sure all 4 edges are touching it. A bit tricky and only as accurate as careful as you are, but close enough to know you are not out a tooth,lol.
crackedback has you covered with his method.
When setting the lifter preload, I use the TDC compression method. A few thousands one way or another is hardly an issue........ IMO.
I run a half turn preload. That way I get a full season or two of QUIET.
